Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and particularly relates to a water treatment defoaming device. Background Art

[0002] In the process of water treatment, wastewater treatment is a crucial link. The wastewater preliminarily treated in the sewage station usually needs to be pressurized by a water pump and transported to the pipeline of the sewage treatment plant for further in-depth treatment. In this process, due to the pressurization of the water pump, a large amount of air will be dissolved in the wastewater. In addition, when the pressurized wastewater flows from the pipeline into the wastewater tank, due to the influence of flow velocity and surface tension, the wastewater collides violently with the water surface of the wastewater tank, and then a large amount of foam is generated;

[0003] The existence of these foams not only affects the visual effect of wastewater treatment, but more importantly, if the defoaming treatment is not carried out in time, the foam may quickly accumulate and block the drain outlet, resulting in a slowdown of the wastewater flow velocity and even causing wastewater overflow, which has an adverse impact on the surrounding environment. Therefore, finding an effective defoaming method has become an urgent problem to be solved in the field of water treatment;

[0004] At present, there are already some defoaming technologies on the market, but they all have some obvious disadvantages:

[0005] For example, the method of using a defoaming agent for defoaming. Although this method is simple and easy to implement, the cost of the defoaming agent is relatively high, and different types of wastewater may require different types of defoaming agents, which increases the complexity of use. At the same time, the addition amount of the defoaming agent also needs to be strictly controlled. If too little is added, the defoaming effect will be poor, and if too much is added, it will cause waste;

[0006] Another common defoaming method is spray defoaming, which breaks the bubbles floating on the water surface through high-speed sprayed water flow or water droplets. Although this method can reduce the number of bubbles to a certain extent, it cannot fundamentally solve the problem of foam generation. In addition, spray defoaming also requires additional equipment investment and consumes a large amount of electric energy, thus increasing the overall cost of water treatment;

[0007] Therefore, in view of the deficiencies of the existing technology, it is necessary to propose a new water treatment defoaming technology. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a water treatment defoaming device, which can effectively defoam the bubbles generated in the water treatment process through physical methods, is not only simple to operate and low in cost, but also can be widely applied to the defoaming treatment of various substances of wastewater.

[0009] The technical solution adopted by the utility model is specifically as follows:

[0010] A water treatment defoaming device includes a sewage tank. In the middle of the inner side of the sewage tank, a partition is assembled. The partition divides the inside of the sewage tank into a water inlet chamber and a water passing chamber. At the bottom end of the inner wall of the sewage tank and at a position where the water passing chamber is far from the partition, a drain port is provided;

[0011] A water passing structure is arranged inside the partition.

[0012] The water passing structure includes a plurality of water flowing holes, which are arranged inside the partition and close to the bottom end.

[0013] A plurality of anti-overflow holes are arranged inside the partition and close to the top end.

[0014] At the bottoms on both sides of the partition and respectively inside the water inlet chamber and the water passing chamber, reinforcing bottom plates are fixed. At least two reinforcing ribs are arranged between the partition and the reinforcing bottom plates.

[0015] The partition is made of PP board.

[0016] A rotating water flowing groove is arranged inside the water flowing hole.

[0017] The technical effects achieved by the present utility model are as follows:

[0018] By arranging a partition with water flowing holes at the bottom inside the sewage tank in the present utility model, the foam is blocked by the partition, and the bubbles generated in the water treatment process are effectively defoamed by a physical method. This device is not only simple to operate and low in cost, but also can be widely applied to the defoaming treatment of waste water of various substances, and has broad market prospects and application value.

Specific embodiments

[0026] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0027] Embodiment 1:

[0028] As Figures 1-4 shown, a water treatment defoaming device includes a sewage pool 1. A partition board 3 is assembled in the middle of the inner side of the sewage pool 1. The material of the partition board 3 is a PP board. Through this setting, the partition board 3 has the advantages of being green, environmentally friendly, highly practical, widely used, and low in manufacturing cost. The partition board 3 divides the inside of the sewage pool 1 into a water inlet chamber 5 and a water passing chamber 6. The user can set the sewage discharge pipe 2 above the water inlet chamber 5, and the sewage 12 can be discharged into the water inlet chamber 5 through the sewage discharge pipe 2, thereby avoiding the presence of foam 13 inside the water passing chamber 6. A drain outlet 4 is provided at the bottom end of the inner wall of the sewage pool 1 and at a position where the water passing chamber 6 is away from the partition board 3.

[0029] A water passing structure is provided inside the partition board 3, and this water passing structure is used to guide the sewage 12 inside the water inlet chamber 5 to the inside of the water passing chamber 6.

[0030] Through this setting, when the sewage discharge pipe 2 discharges the sewage 12 into the inner side of the water inlet chamber 5, the sewage 12 and the foam 13 inside the water passing chamber 6 can be avoided from synchronously existing through the blocking of the partition board 3. And through the water passing structure provided on the partition board 3, the water passing structure can discharge the sewage 12 into the water passing chamber 6 and discharge the sewage 12 through the drain outlet 4. Reinforced bottom plates 9 are fixed at the bottoms on both sides of the partition board 3 and are respectively located inside the water inlet chamber 5 and the water passing chamber 6. At least two reinforcing ribs 10 are provided between the partition board 3 and the reinforced bottom plates 9. Through the setting of the reinforced bottom plates 9 and the reinforcing ribs 10, the reinforced bottom plates 9 and the reinforcing ribs 10 can strengthen the impact force of the partition board 3 against the sewage 12, and reduce the situation that the partition board 3 is inclined or damaged due to the strong impact force of the sewage 12 over time.

[0031] Refer to the attached Figures 2-4, the water passing structure includes a plurality of water flow holes 7, which are arranged inside the partition plate 3 and close to the bottom end. Through this setting, the water flow holes 7 can discharge the sewage 12 at the bottom end of the water inlet cavity 5 to the water passing cavity 6, while the sewage 12 at the top end and the foam 13 thereon cannot contact the water flow holes 7, thereby reducing the discharge rate of the foam 13 through the water flow holes 7.

[0032] Embodiment 2:

[0033] Based on Embodiment 1, this embodiment makes further technical improvements, and its technical structure and effects are as follows:

[0034] Refer to the attached Figure 4 , a plurality of anti-overflow holes 8 are arranged inside the partition plate 3 and close to the top end. Through the setting of the anti-overflow holes 8, when the sewage 12 is at the same height as the anti-overflow holes 8, it can be discharged into the water passing cavity 6 through the anti-overflow holes 8, reducing the phenomenon of overflow caused by the excessive sewage 12.

[0035] Embodiment 3:

[0036] Based on Embodiments 1 and 2, this embodiment makes further technical improvements, and its technical structure and effects are as follows:

[0037] Refer to the attached Figure 5 , a rotating water flow groove 11 is arranged inside the water flow hole 7. Through the setting of the rotating water flow groove 11, the flowing water inside the water flow hole 7 can follow the flow direction of the rotating water flow groove 11 and make a rotating flow, thereby accelerating the flow rate of the sewage 12 inside the water flow hole 7.

[0038] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special description and limitation.
